NOTE:
 Always observe the recommended maximum charging current of the rechargeable
batteries. In general, 200 mA is a recommended charging current if rapid charging is not
necessary. It is definitely safe and optimum to the life of the rechargeable batteries.
 It may be necessary to charge and discharge new rechargeable batteries several times in
the beginning before the optimum capacity of the rechargeable batteries can be
obtained. Use the "Refresh" mode after new rechargeable batteries have been used
under load and charged several times in order to achieve the optimum battery capacity.

show ―null‖ on LCD.
